The Theory of Money and Credit - Ludwig von Mises [121]
While all other credit transactions may occur singly and be per formed on both sides by persons who do not regularly occupy themselves with such transactions, the provision of credit through the issue of fiduciary media is only possible on the part of an undertaking which conducts credit transactions as a matter of regular business. Deposits must be accepted and loans granted on a fairly considerable scale before the necessary conditions for the issue of fiduciary media are fulfilled. Notes cannot circulate unless the person who issues them is known and trustworthy. Moreover, payment by transfer from one account to another presupposes either a large circle of customers of the same bank or such a union of several banking undertakings that the total number of participants in the system is large. Fiduciary media can therefore be created only by banks and bankers; but this is not the only business that can be carried on by banks and bankers.
One branch of banking business deserves particular mention because, although closely related to that circle of banking activities with which we have to deal, it is quite without influence on the volume of money. This is that deposit business which does not serve the bank as a basis for the issue of fiduciary media. The activity carried on here by the bank is merely that of an intermediary, concerning which the English definition of a banker as a man who lends other people's money is perfectly apt. The sums of money handed over to the bank by its customers in this branch of business are not a part of their reserves, but investments of money which are not necessary for day-to-day transactions. As a rule the two groups of deposits are distinguished even by the form they have in banking technique. The current accounts can be withdrawn on demand, that is to say, without previous notice. Often no interest at all is paid upon them, but when interest is paid, it is lower than that on the investment deposits. On the other hand, the investment deposits always bear interest and are usually repayable only on notice being given in advance. In the course of time, the differences in banking technique between the two kinds of deposit have been largely obliterated. The development of the savings-deposit system has made it possible for the banks to undertake the obligation to pay out small amounts of savings deposits at any time without notice. The larger the sums which are brought to the banks in the investment-deposit business, the greater, according to the law of large numbers, is the probability that the sums paid in on any particular day will balance those whose repayment is demanded, and the smaller is the reserve which will guarantee the bank the possibility of not having to break any of its promises. Such a reserve is all the easier to maintain inasmuch as it is combined with the reserve of the current-account business. Small business people or not very well-to-do private individuals, whose monetary affairs are too insignificant to be transferred as a whole to a bank, now make use of this development by trusting part of their reserve to the banks in the form of savings deposits. On the other hand, the circumstance that competition among banks
